Specification of Letters Patent.

Patented lFeb. 9., 1915..

Application filed May le, 1913. Serial No. 768,444.

T0 all whom 'it may concern Be it known that l, CHARLES T. CHILDERs, a citizen of the 'United States, residng in Galesburg, in the county of Knox and State of Illinois, have invented a new and useful Improvement in Bungs, of which the following is a specication.

'Ihis invention relates to improvements in bungs.

One object of the invention is to provide a bung composed of two members having a universal joint therebetween, one of said members being threaded and adapted to be screwed into a bung-hole bushing of a barrel, the other member having a sealing flange adapted to seat on a cooperatingv flange of the bushing to thereby insure a perfect seal at the bunghole.

Another object of the invention is to provide a bung which is constructed ot metal, which is cheap to manufacture and composed of few parts, and which has one member thereoi universally self-seating on uneven surfaces surrounding the bung-hole to thereby provide a perfect seal. or closure for, a barrel or other container, the bung being more particularly designed for use in connection with metallic barrels for carrying gasolene and other inflammable liquids.

The invention furthermorefconsists in the improvements in the parts and devices and in the novel combinations of the parts and devices asl herein shown, described or claimed.

ln the drawing forming a part of this specification, .Figure 1 is a diametrically sectional view ,of the bung embodying my improvements, the same being shown in place on a portion of a barrel or-other container; Fig. 2 is a horizontal sectional view taken substantially on the line 2--2 of Fig. 1; Fig. 3 is anothery horizontal sectional view takenpon line 3-3 of F ig. 1 and Fig. 4t is a view similar to Fig. 1 and showing the manner in which the bung will hermetically seal or' close the bung-hole of a. barrel in which the -flange of the bushing is uneven or irregular relatively to the threaded portion thereof. l

ln said drawing a portion 'of a metallic barrel is shown at 10, the same being provided with a' hole in which is seated an interiorly threaded bushing 11, the latter having a flange 12, said bushing being welded or otherwise suitably secured to the bar*- rel 10 in any well-known manner. As will be apparent, in some instances the threaded portion for receiving the bung may be formed integral with the metal forming the barrel.

The improved bung comprises an exterii orly threaded plug 13 adapted to be threaded into the threadedportion 11 of the bushing, said plug 13 having an angular socket 14 in which is seated a corresponding angular boss l5 formed on the underside of a sealing disk 16` having a flange 17 and preferably provided with a sealing liber washer 18 for engaging with the llange 12 of the bushing. The disk 16 is provided with a squared head 19 adapted to receive a wrench or other implement whereby the bung may be screwed into place. The disk at 16 is provided lwith a. threaded socket 20 in which is threaded a bolt 21, the latter passing through an enlarged recess 22 in the plug 13 and having a shoulder 23 which engages the under face of the boss 15.

As will be understood, the boss 15 is made somewhat smaller than the socket 14 so that there will be a certain' amount of play between the two members 13 and 16 to thereby allow of a universal adjustment therebetween, and on account of the angular formation of the socket 14 and boss 15 a rotation of the disk A16- will rotate with it the threaded plug 13 and as the parts are screwed into place. the plug-13 will move farther inward within the sleeve 11 thereby pulling down with it the disk 16 through .the bolt 21 and clamping the latterlirmly on the flange` 12.

In transporting inflammable liquids, such as gasolene for instance, it is absolutely essential that a perfect seal be formed at the bung ot' the barrel. and as will be understood it is nott feasible or practical to use rubber or other substance to' form the bung since the same are readily attacked by the contents and are soon renderedMunfit for further use. `Where a. metal bung is employed it is essential that some means be provided for compensating for unevenness or irregularities in the surface surrounding the bung-hole in order to, insure a perfect seal`r and on account of the universal adjustment between the plug 13 and disk 16, such l have descrbefLit is possible to seal the bung even when-theilangc of the bushing is uneven or when the bushing is not properly tapped at alright angle to the llO plane of the flange,

which frequently occurs in barrels employing a threaded bung.

Although l have herein shown and described what I now consider the preferred embodiment of my improvements, yet it will be understood that various changes and modifications 'may be construction, particularly in the method of -uniting the plug and disk so that the same have a universal joint therebetween, without. departing from the spirit of the invention, and all suchf changes and modifications are contemplatedthat come yWithin the scope of the claims appended hereto.

I claim:

l. A self-seating rotatable bung including, in combination: an exteriorly threaded rotatable plug adapted to coperate with an interiorly threaded bushing; a sealing disk rotatable with said plug;- and means of uniting said disk and plug permitting'a limited .amount of oscillation therebetween, substantially as specified.

2. A self-seating bung for a receptacle having an internally threaded aperture and including in combination: tw'o members having a universal joint connection therebetween, one of said members carrying a sealing flange and the other being threadedto engage in said aperture, and means by which bcth said members may be rotated frdm a single side, substantially as specified.

3. A self-seating bung including, in combination: an exteriorly threaded .plug;`a sealing disk rotatable with said plug; and means of uniting said disk and plug permitting a limited amount of oscillation therebetween, said means including an angular socket formed in one of said members and anangular boss formed onthe other of said members seated in such socket, substantially as specified.

4. A self-seating bung for a receptacle having an internally threaded a erture and including, in combination: a anged disk and a threaded plug universally and demade in the details of tachably joined together; and means on said disk by which the same is adapted to be rotated, substantially as specified.

5. A self-seating rotatable bung including, in combination: a flanged disk; an exteriorly threaded rotatable plug adapted to coperate with an interiorly threaded bushing; a bolt threaded into one of said members and passing through an enlarged recess in the other of said members for attaching the same together; and means by which said gisk may be rotated, substantially as speci- '6. A self-seating bung including, in combination: an exteriorly threaded plug adapted to be screwed into a threaded bunghole bushing; a flanged disk provided with a sealing gasket adapted to coperate with said bushing; and means for connecting said plug and disk together, with a universal joint, with the disk outwardly of or above said plug, substantially as specified.

7. A self-seating bung including, in combination: an exteriorly threaded plug having an enlarged recess therein; a flanged disk having a sealing gasket; an angular boss formed on said disk and adapted to be seated in a correspondingly formed socket in said plug; and a bolt passing through said recess in the plug and threaded into the disk, substantially as specified.

8. A self-seating bung including in combination an exteriorly threaded plug adapted to be screwed into a threaded bung-hole bushing, a flanged disk provided with a sealing gasket adapted to coperate with said bushing, and means for connecting said plug and disk together with a universal joint, the disk being disposed outwardly of or above said point, substantially as specifled.
